The Pope Bus is inspired by Pope Francis' own transportation preferences. When a cardinal in Buenos Aires, he gave up his chauffeured limousine and opted to ride the bus to work. Before accepting the Popedom, he insisted that the provision of a Pope Bus – with bullet-proof viewing chamber included – be written into his contract. And so it was.

Known for his humility and consideration of the less fortunate, Pope Francis says he hopes his new Pope Bus will provide service and comfort to the less fortunate of the world.

"If I'm going to be paraded across town like a museum exhibit, I might as well help get some people to work while I'm doing it," said the Pope in a telephone interview from a payphone newly installed by his request in Vatican City.

There will be no eating, drinking or loud music on the Pope Bus, and all riders must be wearing shoes and shirts. "All passengers must exit through the rear door," added the Pope.
